To all whom it may concern:

Be it known that I, JOHN C. GEBHART, a

a citizen of the United States, residing at Eagle Rock, in the county of Los' Angeles and State of California, have invented new and useful Improvements in Machines for Ieasuring Textile Fabric, of which the fol'- lowing is a specification.

This invention relates toan improvement in machines for measuring textile fabric of the general type disclosed in my U. S. Letters Patent No. 1,259,389, granted March '12, 1918, and characterized by the provision of a knife for slitting the margin of the goods to indicate the line along which the measured length is to be cut or torn from the rest of the fabric, of an arm for effecting the separation or spacing of the rollers between which the fabric is drawn, one of said rollers functioning as a power roller, and of concentric shafts which carry the knife and the arm, respectively.

The invention is directed more particularly to the arrangement of the knife and its associated elements in the structural combination referred to, and its principal objects are to provide for easy access to the knife for the purpose of renewing or sharpening the same or the stationary blade coiiperating therewith, and also to provide a novel ar rangement of guard which normally protects the knife and the stationary blade against damage and which also prevents the knife from causing injury to persons or material adjacent the machine. I I

According to the invention,the arm for the spacingof the rollers and ,the parts associated with said arm are located within the main casing of the machine, as in my patent referred to, and the knife and the stationary blade are located externally of said casing but within a housing fitted to said casing and which functions as a guard, the organization being such that the housing may be readily removed, and the knife and the associated stationary blade are conveniently accessible for sharpening or renewal upon the removal of the housing.

An embodiment of the invention is illus trated in the accompanying drawings, wherein Figure 1 is a side elevation of a machine in which the features of the invention are incorporated, the housing which incloses the knife and the stationary blade being shown 'mally elevated position wherein the roller 2 MACHINE FOR MEASURING TEXTILE FABRIC.

partly in'section and partly broken away to show the locking levers.

Fig.2 is a detail sectional view on the line 22ofFig.1. i

Similar characters of reference designate correspondingparts in both of the views.

The machine to which the improvements of the present invention are especially applicable includes upper and lower rollers 1 and 2 between which the fabric to be measured is drawn, the upper roller 1 functioning as a power roller for the operation of the measuring instrumentality (not shown). Thelower roller 2 is suitably mounted in a carrier 21 which follows the construction shown in my patent referred to, that is to say, said carrier is formed as a pivotally mounted rectangular frame and is urged by a suitable spring (not shown) to a noris pressed against the'roller 1 or against the fabric interposed between it and the roller 1, as shown in Fig. 1. The carrier 21 is arranged within the maincasing 17' of the ma-- chine, said casing inclosing a frame 18 for the support of certain of the operating parts. The arm 23 by which the carrier is depressed is mounted, within-the, casing 17 upon a transverse shaft 111,1which externally of said casing carries an' operating lever 112. The movable knife 22 is mounted on a tubular rock shaft 148 which surrounds theshaft 1110f the arm 23 and externally of the casing carriesan operating lever 149. As in my prior patent referred 0 to, an element 24 is preferably employed to prevent a simultaneous operation of the arm '23 and knife 22; said element is pivoted at' its rear end for horizontal swinging 'movement and is normally held' centered by springs 150 engaging its pivoted heel por-] tion;' 'atits front end it-has a transverse head 151 (shown'infdotted lines, F ig, 2) for cooperation with upright arms 152 and 153 mounted on or movable with the shafts 111' and 148, respectively;v said arms being disposed at opposite sides of the element 24 and having confronting cam faces 154 for engagement with the head 151. The Openatinglevers 112 and 149 are arranged in adjacency and the element 24 prevents their simultaneous operation but enables either of them to be independently operated. Thus, if the lever 112 be depressedto oper atethe arm-23 and also the carrier 21,. the 0 arm 152, acting on the head151, will swing the element 24 to project said head across the path of the arm 153, the head thus functioning as a lock for the arm 153 and the parts associated therewith, so long as the arm 23 is held lowered; in like manner, if the lever 149 be depressed to operate the knife 22, the arm 153, acting on the head 151, will swing the element 24 to project said head across the path of the arm 152, the head thus functioning as a lock for the arm 152 and the parts associated therewith so long as the knife 22 is held lowered. If

1 casing 17 but within a housing 155 removably'secured to said casing as by fastening screws 156, said housing having a slot 157 registering with the slot 19 of the casing 17, and belowsaid slot carrying the fixed blade 158, preferably secured by screws 159 and with which the knife 22 coiiperates, the

material to be measured, of course, being drawn through the slots 19 and 157. The knife 22 is preferably composed of a blade .22 and an arm 22 to which said'blade is secured by screws 22, and the arm 22 has a hub 22 which is. preferably keyed to the shaft 148 so as to turn with said shaft but be removable therefrom; andthe blade 22 is pressed toward the fixed blade 158 by a spring 160 surrounding the shaft 148 and arranged between the hub 22 and the frame, .18. The'spring 160 preferably has a seating in a recess or opening 161 formed in the casing 17 concentric to the shaft 148 and is arranged to acttorsionally on said shaft or the hub 22 keyed thereto in order to hold the knife 22 in a normally elevated position and to return said knife and the operating 7 -leve-r 149 to said position after each operation thereof. The levers-112 and 149 are, of course, mounted externally of the housing 155 andare held against endwise displacement from the respective shafts 111 and 148 by a nut 162 secured to the end of the shaft 7 @111. .The housing 155 normally protects '7 65' the blades 22 'and 158 against damage by contact with othe'r' objects and also serves as a safety guard for the protection of the clerk or other person happening to be near the -machine, as well as for preventing the knife from catching against and injuring any fabric or other material that may be lying on the counter near the machine. On the removal of the nut 162 and the removal of the housing 155' from the casing 17 the blades 22 and 158 are readily accessible for the purpose of sharpening or renewal.
